Your Guide to Regrouting Tiles

Grout does not last forever – it will erode, get chipped and could be damaged by mould or damp. The grout wearing down not only makes your wall or floor look worn, it’s also a warning sign for your tiling. Ensure that your tiling remains in good condition by regrouting it.

Perhaps your grout is looking worn and shabby or maybe you want a new colour that will go better with the tiling – you can choose from a surprising amount of colours when it comes to grout. Whatever your reasoning, this guide will make it easy for you to regrout your tiles with as little stress as possible.

What you’ll need:

  • Grout
  • Dust mask
  • Safety goggles
  • Knee pads
  • Dust sheet
  • Latex gloves
  • Mixing bucket
  • Trowel
  • Grout rake/automatic grout remover
  • Grout float
  • Sealer

Remove the old grout

First things first, don your protective gear and lay down your dust sheet if you’re dealing with a tiled wall. This is messy work that kicks up dust and debris, so you need to make sure you are suitably protected. The dust sheet will make cleaning up afterwards far easier. Knee pads are a lifesaver when it comes to DIY. I remember the painful days before I was convinced of the necessity of knee pads.

Use the grout rake to scrape away the old grout. Get right in there and scrape in the direction that the teeth of the rake point, and only in that direction. It is advisable to have spare rake blades handy, because they’ll wear out after a bit and the more blunt they are, the longer the work will take.

This is strenuous work that will require you to take breaks if you’re removing the grout from a large area of floor or wall, unless you're using an automatic grout remover. It's helpful to have a friend or two to help since it’s an easy task to explain and will make things much quicker. As you work, clean away any grout residue or debris using a damp sponge.

Apply the new grout

Clean everything up to ensure that there’s no dust or old grout in between the tiles. Mix the grout in the bucket, as per the manufacturer’s instructions, using the trowel to stir the mixture. Normal rule of thumb is to make the mixture a bit thicker than smooth peanut butter. Pour a generous amount onto your grout float ready for application.

Use your float to apply the grout in between the tiles. Push the grout across the tiles in a diagonal directional to effectively get it into the gaps. Use the rubber side of the float to press the grout into the gaps and give it an even finish Wipe away any mess or excess grout from the surfaces of your tiles with a damp sponge as you go before it can dry.

Clean up and seal

Wait for the grout to dry (for however as long as the manufacturer advises). Give the whole tiling area a wipe with a sponge and cold water to get rid of dust and debris. Make sure the sponge is regularly cleaned to ensure you’re not just pushing grout around on the surface of the tiling. Polish the surface with a cloth polish to give it that extra shine.

After the grout has been there for a week, you can seal it to protect it further from damp and mould and make your handiwork last even longer. That’s the final stage – your tiles have now been regrouted, leaving your wall or floor looking newer in great condition.
